These points are also on the negative side of the x axis, at -pi/4 and -pi/2. When we move along the x axis, notice what happens to the y value. On the left side of zero, tangent is negative. At x=-pi/4, tangent=-1.
The Independent Online. David Cameron may have called a referendum on the EU to blackmail Europe, according to Vladimir Putin. The Russian president also questioned Mr Cameronâs decision to call the vote, as it has caused a âgreat problemâ.
No one really knows but it is possible for the trample of the Russian constitution has happened many times and the majority haven't seemed to care or notice. You need to understand that if Putin would want to re-elect in 2018 he'd be supported by millions (Russians). It all depends on whether he decides to run. My sense is that he is worn out, and will not run if at least two other credible candidates appear.
